We recently published the latest article by Chris Vandersluis to the "From the Trenches" column on the Microsoft Project Server 2010 TechCenter. In this latest article - "EPM-Centralized or Decentralized?"- Chris talks in detail about the how organizations need to understand the problem they are trying to solve when deciding on implementing a project management system. Sometimes deploying a centralized project management system may not be the best answer.
Chris has a unique conversational tone in this writing style, and backs that up with many years of EPM solutions implementation knowledge and experience. If you haven't read any of his articles yet, please take a look. It will be well worth your time!
